Cheers guys, all good points and some I've half considered,
The internet here is shocking and I don't get a great phone signal so I have an auto divert from my mobile to landline when I'm at home but I guess I'll just change the answerphone message and hide the handsets.
There's desktop and mobile editor views which appear fine from here but I'll do the map externally and merge the images should fix that bit.
The overall colour is supposed to be the sunny yellow (I think they call it) you sometimes see VW vans in. I wonder if changing the colour settings will make it a little more consistent, I don't know how many options there are with the Wix editor.
MI'll keep my eyes out for a BG RCBO as well, just as not to bug anyone else, I'm not wholly convinced many would notice though
Fitting mismatched components would probably be against both manufacturer's instructions and advice. Do they fit exactly and have been made to be compatible ? The issues here are not likely to be cosmetic but more of a fire hazard nature.
